got a skip under load

i have noticed a skip when i get on to it and its getting worse, i changed fuel filter and is still the same, it does fine when driving normal. the tranny shifts fine under normal and seems to act up when i get on it as well.this is on a 03. i had it studded,egr deleted, 8new injectors, IRP valve, ICP sensor, UVC harnesses and and a new hp oil pump back in dec 09 and the truck has only been driving 7k miles since then. i put it back to stock tune and it still does it. any thoughts

I'll assume your '03 is the 6.0?

Is it the engine skipping or the trans? How many miles are on it?

Truck has 128k and the tranny has around 15k. it is deffintely something with the engine and not the tranny. I am thinking maybe fuel pressure related but not sure. I am going to my 6.0 guy tomorrow and hopefully he will get it figured out, he is also thinking fuel pressure from what i am telling him by phone.he is going to bring the ford laptop and program home with him, if it is the fuel pump going then i will just go ahead and do a AirDog system.
